TPS22810: Test setup for measuring Vout fall time

Takahiro Saito

Part Number: TPS22810

Hi team,

The datasheet describes Vout fall time in section 7.6. The test circuit on Fig.16 for this specification does not show the connection of QOD pin.

Could you clarify the connection between QOD and VOUT in the test circuit?

Hi Saito,

For this parameter the QOD pin is left disconnected. However, even if the 250Ω QOD pulldown resistance was connected to the output, the 10Ω load would still dominate the output discharge / fall time.

Thanks,
